Students often have to engage in what we call convergent retrieval, the kind of memory called upon when there is only one possible correct answer, with no latitude whatsoever.

In his 2003 book Life's Solution: Inevitable Humans in a Lonely Universe, Conway Morris assembled a collection of examples of what is called convergent evolution.
Sadly for some though not me, the greatest recent example of an ensemble movie that does do not do this is, and still values the idea of convergent narrative strands is still Love Actually.
Almost in the next moment, though, I was reminded of something in biology called convergent evolution, which is the process whereby organisms not related to each other, separated by continents, even, independently evolve similar traits.
You can go to this Web site and pay $5.95 for a bag of 1,500 adult ladybugs, known as convergent ladybird beetles.
Through the process of natural selection, it finds new uses for existing features, often resulting in what is known as convergent evolution -- the development of similar biological traits in different orders of animals, such as powered flight in birds and bats.
It's called convergent evolution, species that evolve in separate habitats, but because of the same threats, obstacles, and problems to overcome, they develop the same practical, advantageous traits and end up being almost identical.
My original edit:Sometimes called convergent recruitment, this is the current trend that is going against the assumption of common descent.
Creationists assert that since bats, birds, and pterosaurs do not share a common ancestor, their wings originated separately from each other; assert that since bats, birds, and pterosaurs do share a common ancestor, but that ancestor did not have wings, then each line developed the structures independently -- a hypothetical process known as convergent evolution.
